Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. Stonemasonry is the craft of shaping and arranging stones, often together with mortar, to form structures.


The basic tools, methods and skills of the banker mason have existed as a trade for thousands of years. It is one of the oldest activities and professions in human history. Many of the long-lasting, ancient shelters, temples, monuments, artifacts, fortifications, roads, bridges, and entire cities were built of stone. Famous works of stonemasonry include Göbekli Tepe, the Egyptian pyramids, the Taj Mahal, Cusco's Incan Wall, Easter Island's statues, Angkor Wat, Borobudur, Tihuanaco, Tenochtitlan, Persepolis, the Parthenon, Stonehenge, the Great Wall of China, Chartres Cathedral, and the Stari Most.

  1. Quarryman split sheets of rock, and extract the resulting blocks of stone from the ground. This type of stonemason works in a quarry to extract chunks of stone. These rough pieces are then collected and transported away from the extraction surface for further refinement. [1]
  2. Sawyer cut these rough blocks into dimension stone, to required size with saws. The resulting block if ordered for a specific component is known as sawn six sides (SSS). A sawyer mason is similar to a banker mason (see below) in that they work with rough pieces of stone and shape them according to certain standards. [1] The main difference between a sawyer mason and a banker mason is the size of the stone they work with – a sawyer mason typically works with much larger pieces and uses diamond-coated tools. Sawyer masons may work in quarries or be found in tile or flooring stores, possessing a range of specific skills, such as examining grain patterns to determine cleavage, creating smaller stones from larger pieces, and carving precise outlines and drilling holes using various tools like chisels.
  3. Banker mason , sometimes referred to as a bank mason, is workshop-based, and specializes in working the stones into the shapes required by a building's design, [2] this set out on templets and a bed mould. A banker mason uses various hand and power tools to cut, carve, and shape stone. They can produce anything from stones with simple chamfers to tracery windows, detailed mouldings and the more classical architectural building masonry. When working a stone from a sawn block, the mason ensures that the stone is bedded in the right way, so the finished work sits in the building in the same orientation as it was formed on the ground. Occasionally though some stones need to be oriented correctly for the application; this includes voussoirs, jambs, copings, and cornices. The stone's size and shape are usually predetermined by builders or other parties involved in a project, and the banker mason works according to a brief or a set of designs provided for that project. Once the stone has been crafted to the required specifications, it is transported to the construction site or another location for use in a building or other structure.
  4. Fixer mason specializes in the fixing of stones onto buildings, using lifting tackle, and traditional lime mortars and grouts. [3] Sometimes modern cements, mastics, and epoxy resins are used, usually on specialist applications such as stone cladding. Metal fixings, from simple dowels and cramps to specialized single application fixings, are also used. The precise tolerances necessary make this a highly skilled job. This type of masons have specialized into fixing the stones onto the buildings. A fixer mason is responsible for traveling to a job site to fit and lay pre-prepared stone or cladding for buildings. They might do this with grouts, mortars, and lifting tackle. They might also use things like single application specialized fixings, simple cramps, and dowels as well as stone cladding with things like epoxy resins, mastics, and modern cements.
  5. Memorial mason or monumental mason carve gravestones and inscriptions. [1]
  6. Carver mason crosses the line from craft to art. They use their artistic ability to carve stone into foliage, figures, animals or abstract designs. Carver masons are the artists of stonemasonry, responsible for creating designs and/or patterns from stone, as well as on stones. This work can include stone sculptures of figures or animals, or other projects of a similar nature. Throughout history, carver masons have been renowned for their exceptional skills in crafting beautiful pieces from stone. [1]

Ashlar masonry

Stone masonry using dressed (cut) stones is known as ashlar masonry. [4]

Rubble masonry

Use of rubble in masonry: antonymous to ashlar masonry. Can be infill in an ashlar wall, used in cyclopean concrete, and other contexts. [4]

Trabeated systems

One of the oldest forms of stone construction uses a lintel (beam) laid across stone posts or columns. This method predates Stonehenge, and refined versions were used by the Egyptians, Persians, Greeks, and Romans. [4]

Dry stone

Stone walls built without mortar, using the shape of the stones, compression, and friction for stability. [4]

Arch masonry

Note: The Wikipedia page on stone arches is about stone-arch bridges, and the arch page is about all arches, including non-stone. [4]

Cyclopean masonry

Dry wall construction using massive boulders that may have been shaped to fit together. [4]

Polygonal masonry

Very similar to cyclopean masonry, though the boulders are somewhat more shaped into polygonal profiles. [4]

In the modern era, stone has been largely relegated as a cosmetic element of buildings, often used as decorative cladding on steel-reinforced concrete. This is despite its wide historical use in large compressive structures: 50-m bridges and colosseums in Roman times, ~65-m tall cathedrals since the middle ages, and 12-story apartment buildings built in the 1690s. [5]

  1. Stone veneer is used as a protective and decorative covering for interior or exterior walls and surfaces. The veneer is typically 1 in (25.4 mm) thick and must weigh less than 15 lb per square foot (73 kg m−2) so that no additional structural supports are required. The structural wall is put up first, and thin, flat stones are mortared onto the face of the wall. Metal tabs in the structural wall are mortared between the stones to tie everything together, to prevent the stonework from separating from the wall.
  2. Massive precut stone. Also known as "prefabricated stone", "massive stone", "pre-sized stone", or "pré-taille" stone. Main page: Massive precut stone.
  3. Formwork stone. "Pierre banchée" in French. Uses stone tiles or ashlars as shuttering for pouring concrete. These are left in place after the concrete sets. This is the inverse procedure to stone cladding, where the stone tiles are attached to the concrete after the temporary shuttering has been removed. Developed by Fernand Pouillon to accelerate construction. [6] Formwork stone is distinct from cyclopean concrete in that the former uses rectilinear tiles, while the latter uses boulders and/or cobblestone.
  4. Post-tensioned stone. A high-performance composite construction material consisting of stone held in compression with tension elements. The tension elements can be connected to the outside of the stone, but more typically uses tendons threaded internally through a duct formed from aligned drilled holes.
  5. Pre-tensioned stone. Using an epoxy shear connector, early experiments have shown that it is possible to pre-tension stone, maintaining the tendon under tension while the liquid epoxy is injected and allowed to set. [7]
  6. Cyclopean concrete. This method uses a combination of cyclopean masonry and rubble masonry: boulders and or rubble are placed in a form (or in a ditch), and concrete is poured on top to bind the stones together before removing the form. [8] Variations of this include Frank Lloyd Wright's 'desert masonry' [9] and Institut Balear de l'Habitatge's cyclopean concrete blocks, which are cast in a large slab and precisely sawn for use as prefabricated masonry in the massive precut stone system.
  7. Slipform stonemasonry is a variation of Cyclopean concrete stone-wall construction that uses formwork to contain the rocks and mortar while keeping the walls straight. Short forms, up to two feet tall, are placed on both sides of the wall to serve as a guide for the stonework. Stones are placed inside the forms with the good faces against the formwork. Concrete is poured behind the rocks. Rebar is added for strength, to make a wall that is approximately half reinforced concrete and half stonework. The wall can be faced with stone on one side or both sides. [10]
  8. Digital stereotomy. Using CAD and computer models of load, modern designers are able to cut complex vaults, arches, and other arrangements of precisely cut ashlars. [11] Antecedents to this discipline include curved vaults, and also flat vaults that use a concentric flat arch vault and the Abeille flat vault. [12] [13] Using digital design and machining, such compression structures can be shapes into complex compressive structures. [14]
  9. Trabeated stone exoskeleton. In the modern era, post-and-lintel construction was adapted use as a stone exoskeleton in the design of 15 Clerkenwell Close. [15] The stone exoskeleton method is a variant of the massive precut stone method: the ends of the posts and lintels are precisely precut offsite prior to assembly by crane. At least two more trabeated stone exoskeleton high-rise buildings are underway, one in London, [16] and another in Bristol. [17]

Massive precut stone

Massive precut stone is also known as "prefabricated", or "pre-sized" stone is a modern method of building with load-bearing stone. [18] Precut stone is a DFMA construction method that uses large machine-cut stone blocks with precisely defined dimensions to rapidly assemble buildings in which stone is used as a major or the primary load-bearing material.

Massive precut stone construction was originally developed by Fernand Pouillon in postwar period who referred to the method as "pierre de taille" or "pré-taille" stone. It became possible through innovations by Pouillon and Paul Marcerou, a masonry engineer at a quarry in Fontvieille, to adapt high-precision saws from the timber industry to quarrying and stone sawing. [19]

The key technique of massive precut (MP) stone is to cut stone ashlars to precise dimensions that match the architect's plan such that the stones can be dropped into place by crane for rapid construction. [18] The blocks may be numbered so that the masons can follow the plan procedurally. The use of massive blocks reduces costs by minimizing sawing and fixer-masonry costs. The use of a crane reduces labor, accelerates construction, and allows the masons to precisely and quickly position the blocks.

Design features of massive precut stone

MP stone is defined by four design attributes.

  1. Load-bearing stone. This distinguishes it from cosmetic precut stone, which is used for cladding decoration. [18] Historically, load-bearing stone is the most durable construction method. [4]
  2. Massive block sizes. The heuristic definition of 'massive stone' is a block that is too heavy to be lifted by hand. Using massive dimensions has three critical benefits: (1) minimizing cuts, which lowers cost and shortens production time, (2) increases the thermal mass of walls for temperature regulation in the building, and (3) makes use of crane construction, thereby lowering manual labor, shortening assembly time, reducing mortar, labor, and cost. [18]
  3. Precise offsite dimension cuts. Precutting can be done at the quarry, or at a masonry workshop by sawyer and banker masons. The precision amounts to a form of prefabrication, such that the masons do not have to make adjustments onsite, and construction is an assembly process. Precise ashlar interfaces also reduces the amount of mortar required. [18]
  4. Design for manufacturing and assembly. The architect will design the building to specify each ashlar's dimensions. Blocks are to be designed to be as modular as possible, ideally with a handful of different shapes. [18] Reducing the types of shape simplifies manufacture. Use of DFMA and modularity improves the chance of project success. [20]

Types of massive precut stone construction

  • Massive precut ashlars. Blocks cut precisely on four to six sides, used to assemble walls, lintels over windows and doors, and in flat arches.
  • End-shaped massive precut posts and lintels. Quarry-finished blocks with precisely shaped ends for assembly into post-and-lintel frameworks.
  • Massive cyclopean concrete blocks. Developed by IBAVI in Mallorca, rough stones are placed in a mold and saturated with concrete. [21] The concrete is sawn into massive ashlars for crane assembly. Enables reuse of rough plum stones from traditional stone masonry.

Benefits of massive precut stone construction

MP stone construction has advantages over conventional masonry and concrete construction.

  1. Build speed. The use of precisely cut and numbered ashlars, combined with crane-assisted assembly, significantly reduces construction time compared to traditional stone masonry techniques. [18] Compared to concrete construction, MP stone is faster as there is no setting wait time.
  2. Cost reduction. Compared to brick masonry or smaller ashlars, using larger stone blocks and thereby minimizing sawing and fixer-masonry costs, the overall expense of constructing a building can be reduced.
  3. Labor Efficiency. The use of cranes and a well-organized construction plan reduces the labor required, lowering costs and reducing the wait time for skilled mason availability.
  4. Design efficiency. The precision of machine-cut ashlars allows for more modularity in design, enabling architects to create building designs quickly. [18]
  5. Durability. Buildings constructed using massive precut stone maintain the inherent durability and longevity of stone construction, offering long-lasting and low-maintenance structures. [4] At least one study of a modern 20-storey unreinforced MP-stone tower has suggested this method has good seismic resilience: "With regard to the current Algerian seismic design regulation, the results obtained in terms of time period, frequency, storey drifts and displacements showed that the… (Diar Es Saada massive precut stone)… tower can be considered as an earthquake-resistant building fulfilling the required structural safety conditions." [22]
  6. Aesthetics. Compared to concrete and other materials, massive precut stone construction yields visually striking and distinctive buildings that showcase the natural beauty of stone. [18] [23]
  7. Environmental Benefits. The use of a material with lower embedded carbon contributes to a more sustainable building process, minimizing the environmental impact. Lower carbon emissions: load-bearing stone construction emits around 1/10th the carbon as a comparable concrete building. [24] As 80% of energy is non-grid fossil fuel, and construction is respoinsible for 8% of carbon emissions, the replacement of coal-burning concrete production with lower-energy dimension-stone production could have a substantial impact on net-zero goals.
  8. Reusability. When a building has reached the end of its usefulness, massive rectilinear ashlars are easily reused in new construction. [18]
  9. Thermal Performance. As with traditional stone construction, massive precut stone buildings benefit from excellent thermal mass, helping to regulate indoor temperatures and reduce energy consumption for heating and cooling. [18]

History of massive precut stone

Fernand Pouillon pioneered the use of massive precut stone in modern architecture. During the post-war period, his innovative approach to stone construction led to the development of numerous noteworthy projects, with a particular focus on housing. Throughout his long career, Pouillon played a crucial role in the development and popularization of massive precut stone construction techniques. His pioneering work laid the foundation for subsequent architects to build upon and innovate, leading to the resurgence and expansion of this construction method in the 2020s, with the rise of interest in low-carbon durable construction.

Post-tensioned stone

Post-tensioned stone is a high-performance composite construction material: stone held in compression with tension elements. The tension elements can be connected to the outside of the stone, but more typically uses tendons threaded internally through a duct formed from aligned drilled holes.

Post-tensioned stone ("PT stone") could consist of a single piece, but drill limitations and other considerations mean it is typically an assembly of multiple components with mortar between pieces. PT stone has been used in both vertical columns (posts), and in horizontal beams (lintels). It has also been used in more unusual engineering applications: arch stabilization, flexible foot bridges, and cantilevered sculptures.

MP stone has a close affiliation with massive precut stone as two central techniques of modern stonemasonry.

"Post-tensioned stone increases the failure load of stone in bending, but also the stiffness of a structure by reducing joint cracking. This method of construction is widely used for concrete structures, but the advantages of using similar techniques with stone are only just being realised.". [25]

Stone has great compressive strength, so is ideal in compressive structures like stone arches. [26] However, it has relatively weak flexural strength (compared to steel or wood), so in isolation cannot be safely used in wide spans under tension. [26]

For concrete, this problem has been long solved: in addition to conventional tensile reinforcement, engineers developed prestressed concrete methods starting around 1888. Such tension-reinforced concrete applications combine compressive strength with pre-stressed tensile compresssion for combined strength much greater than either of the individual components, and have been in wide use for decades. As for concrete, post-tensioning maintains stone in compression, thereby increasing its strength.

Post-tensioning is achieved steel tendons either threaded through ducts within the stone elements or along their surface. Once the stone components are in place, the tendons are tensioned using hydraulic jacks, and the force is transferred to the stone through anchorages located at the ends of the tendons. The tensioning process imparts a compressive force to the stone, which improves its capacity to resist tensile stresses that could otherwise cause cracking or failure.

Energy use and carbon emissions

Stone is 'natural precast concrete' so only needs to be cut (and strength tested) and post-tensioned prior to use in construction. Compared to concrete and steel, post-tensioned stone production has dramatically lower energy costs, with concomitant lower carbon emissions. [27]

Stonemasonry is one of the earliest trades in civilization's history. During the time of the Neolithic Revolution and domestication of animals, people learned how to use fire to create quicklime, plasters, and mortars. They used these to fashion homes for themselves with mud, straw, or stone, and masonry was born.

The Ancients heavily relied on the stonemason to build the most impressive and long-lasting monuments to their civilizations. The Egyptians built their pyramids, the civilizations of Central America had their step pyramids, the Persians their palaces, the Greeks their temples, and the Romans their public works and wonders (See Roman Architecture). People of the Indus Valley civilization, such as at Dholavira made entire cities characterized by stone architecture. Among the famous ancient stonemasons is Sophroniscus, the father of Socrates, who was a stone-cutter.

Castle building was an entire industry for the medieval stonemasons. When the Western Roman Empire fell, building in dressed stone decreased in much of Western Europe, and there was a resulting increase in timber-based construction. Stonework experienced a resurgence in the 9th and 10th centuries in Europe, and by the 12th-century religious fervour resulted in the construction of thousands of impressive churches and cathedrals in stone across Western Europe.

Medieval stonemasons' skills were in high demand, and members of the guild, gave rise to three classes of stonemasons: apprentices, journeymen, and master masons. Apprentices were indentured to their masters as the price for their training, journeymen were qualified craftsmen who were paid by the day, and master masons were considered freemen who could travel as they wished to work on the projects of the patrons and could operate as self-employed craftsmen and train apprentices. During the Renaissance, the stonemason's guild admitted members who were not stonemasons, and eventually evolved into the Society of Freemasonry; fraternal groups which observe the traditional culture of stonemasons but are not typically involved in modern construction projects.

A medieval stonemason would often carve a personal symbol onto their block to differentiate their work from that of other stonemasons. This also provided a simple ‘quality assurance’ system.

The Renaissance saw stonemasonry return to the prominence and sophistication of the Classical age. The rise of the humanist philosophy gave people the ambition to create marvelous works of art. The centre stage for the Renaissance would prove to be Italy, where Italian city-states such as Florence erected great structures, including the Florence Cathedral, the Fountain of Neptune, and the Laurentian Library, which was planned and built by Michelangelo Buonarroti, a famous sculptor of the Renaissance.

When Europeans settled the Americas, they brought the stonemasonry techniques of their respective homelands with them. Settlers used what materials were available, and in some areas, stone was the material of choice. In the first waves, building mimicked that of Europe, to eventually be replaced by unique architecture later on.

In the 20th century, stonemasonry saw its most radical changes in the way the work is accomplished. Prior to the first half of the century, most heavy work was executed by draft animals or human muscle power. With the arrival of the internal combustion engine, many of these hard aspects of the trade have been made simpler and easier. Cranes and forklifts have made moving and laying heavy stones relatively easy for the stonemasons. Motor powered mortar mixers have saved much in time and energy as well. Compressed-air powered tools have made working of stone less time-intensive. Petrol and electric-powered abrasive saws can cut through stone much faster and with more precision than chiseling alone. Cemented carbide-tipped chisels can stand up to much more abuse than the steel and iron chisels made by blacksmiths of old.

Stonemasons use a wide variety of tools to handle and shape stone blocks (ashlar) and slabs into finished articles. The basic tools for shaping the stone are a mallet, chisels, and a metal straight edge. With these one can make a flat surface – the basis of all stonemasonry.

Chisels come in a variety of sizes and shapes, dependent upon the function for which they are being used and have many different names depending on locality. There are different chisels for different materials and sizes of material being worked, for removing large amounts of material and for putting a fine finish on the stone. A drove chisel is used for smoothing off roughly finished stones.

Mixing mortar is normally done today with mortar mixers which usually use a rotating drum or rotating paddles to mix the mortar.

The masonry trowel is used for the application of the mortar between and around the stones as they are set into place. Filling in the gaps (joints) with mortar is referred to as pointing. Pointing in smaller joints can be accomplished using tuck pointers, pointing trowels, and margin trowels, among other tools.

A mason's hammer has a long thin head and is called a Punch Hammer. It would be used with a chisel or splitter for a variety of purposes

A walling hammer (catchy hammer) can be used in place of a hammer and chisel or pincher to produce rubble or pinnings or snecks.

Stonemasons use a lewis together with a crane or block and tackle to hoist building stones into place.

Today power tools such as compressed-air chisels, abrasive spinners, and angle grinders are much used: these save time and money, but are hazardous and require just as much skill as the hand tools that they augment. But many of the basic tools of stonemasonry have remained virtually the same throughout vast amounts of time, even thousands of years, for instance when comparing chisels that can be bought today with chisels found at the pyramids of Giza the common sizes and shapes are virtually unchanged.


Traditionally medieval stonemasons served a seven-year apprenticeship. A similar system still operates today.

A modern apprenticeship lasts three years. This combines on-site learning through personal experience, the experience of the tradesmen, and college work where apprentices are given an overall experience of the building, hewing and theory work involved in masonry. In some areas, colleges offer courses which teach not only the manual skills but also related fields such as drafting and blueprint reading or construction conservation. Electronic Stonemasonry training resources enhance traditional delivery techniques. Hands-on workshops are a good way to learn about stonemasonry also. Those wishing to become stonemasons should have little problem working at heights, possess reasonable hand-eye coordination, be moderately physically fit, and have basic mathematical ability. Most of these things can be developed while learning.

The modern stonemason undergoes comprehensive training, both in the classroom and in the working environment. Hands-on skill is complemented by an intimate knowledge of each stone type, its application, and best uses, and how to work and fix each stone in place. The mason may be skilled and competent to carry out one or all of the various branches of stonemasonry. In some areas, the trend is towards specialization, in other areas towards adaptability.

Today's stonemasons undergo training that is quite comprehensive and is done both in the work environment and in the classroom. It isn't enough to have hands-on skills only. One must also have knowledge of the types of stones as well as its best uses and how to work it as well as how to fix it in place. [29]

Many of the world's most famous buildings have been built of sedimentary stone, from Durham Cathedral to St Peter's in Rome. There are two main types of sedimentary stone used in masonry work, limestones and sandstones. Examples of limestones include Bath and Portland stone. Yorkstone and Sydney sandstone are the most commonly used sandstone.

Masonry is the craft of building a structure with brick, stone, or similar material, which are often laid in and bound together by mortar; the term masonry can also refer to the building units themselves. The common materials of masonry construction are bricks and building stone such as marble, granite, and limestone, cast stone, concrete blocks, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades.

<span class="mw-page-title-main">Inca architecture</span> Pre-Columbian architecture in South America

Inca architecture is the most significant pre-Columbian architecture in South America. The Incas inherited an architectural legacy from Tiwanaku, founded in the 2nd century B.C.E. in present-day Bolivia. A core characteristic of the architectural style was to use the topography and existing materials of the land as part of the design. The capital of the Inca empire, Cuzco, still contains many fine examples of Inca architecture, although many walls of Inca masonry have been incorporated into Spanish Colonial structures. The famous royal estate of Machu Picchu is a surviving example of Inca architecture. Other significant sites include Sacsayhuamán and Ollantaytambo. The Incas also developed an extensive road system spanning most of the western length of the continent and placed their distinctive architecture along the way, thereby visually asserting their imperial rule along the frontier.

<span class="mw-page-title-main">Stone wall</span> Masonry structural division

Stone walls are a kind of masonry construction that has been used for thousands of years. The first stone walls were constructed by farmers and primitive people by piling loose field stones into a dry stone wall. Later, mortar and plaster were used, especially in the construction of city walls, castles, and other fortifications before and during the Middle Ages. These stone walls are spread throughout the world in different forms. One of the best example is the Cyclopean Wall in Rajgir, India.

<span class="mw-page-title-main">Stone veneer</span>

Stone veneer is a thin layer of any stone used as decorative facing material that is not meant to be load bearing. Stone cladding is a stone veneer, or simulated stone, applied to a building or other structure made of a material other than stone. Stone cladding is sometimes applied to concrete and steel buildings as part of their original architectural design.

Opus quadratum is an ancient Roman construction technique, in which squared blocks of stone of the same height were set in parallel courses, most often without the use of mortar. The Latin author Vitruvius describes the technique.

<span class="mw-page-title-main">Rubble masonry</span> Type of building stone

Rubble masonry or rubble stone is rough, uneven building stone not laid in regular courses. It may fill the core of a wall which is faced with unit masonry such as brick or ashlar. Some medieval cathedral walls have outer shells of ashlar with an inner backfill of mortarless rubble and dirt.

The history of construction embraces many other fields, including structural engineering, civil engineering, city growth and population growth, which are relatives to branches of technology, science, history, and architecture. The fields allow both modern and ancient construction to be analyzed, as well as the structures, building materials, and tools used.

Thomas Frazer was an American mason known for his work in Beaver, Utah. Born in Lortny, Scotland, he created many works that are listed on the U.S. National Register of Historic Places.

<span class="mw-page-title-main">Post-tensioned stone</span> Form of stonework used in construction

Post-tensioned stone is a high-performance composite construction material: stone held in compression with tension elements. The tension elements can be connected to the outside of the stone, but more typically uses tendons threaded internally through a duct formed from aligned drilled holes.

<span class="mw-page-title-main">Massive precut stone</span> Type of stonemasonry used in construction

Massive-precut stone is a modern stonemasonry method of building with load-bearing stone. Precut stone is a DFMA construction method that uses large machine-cut dimension stone blocks with precisely defined dimensions to rapidly assemble buildings in which stone is used as a major or the sole load-bearing material.
